PLICA RECTA Meaning and
Definition
-
Plica recta refers to a vertical fold or ridge within the rectum, which is a part of the gastrointestinal system. It is a distinguishing anatomical feature that aids in the identification and understanding of the rectum's structure and function.
The rectum is the final segment of the large intestine, connecting the sigmoid colon to the anal canal. The plica recta, also known as the rectal fold or rectal valve, is located within this segment. It is characterized by a vertical fold of mucous membrane that extends across the interior circumference of the rectal lumen.
This fold is lined with specialized epithelial cells known as columnar epithelium, which secrete mucus to aid with the passage of feces through the rectum and facilitate smooth bowel movements. The plica recta may also contain blood vessels, nerves, and lymphatic tissue, contributing to the rectum's overall functionality.
While the precise function of the plica recta remains somewhat unclear, it is believed to play a role in preventing fecal incontinence. By creating an impediment for feces to traverse easily, the plica recta helps maintain control over bowel movements and promotes adequate stool retention until defecation is initiated voluntarily.
